ABSTRACT- Apart from the northern coast, most of Egypt is desert. However, the northern coastal region experiences some precipitation mainly during winter. We investigate the variability of wintertime (December, January and February) precipitation in North Egypt during the 39-yr interval 1961-1999 and its relationship with the North Atlantic Oscillation during autumn and winter. We have used the time series formed of winter season ranked precipitation to study the variability. Also, the correlation coefficient technique is used to study the relationship between precipitation and North Atlantic Oscillation. Precipitation varies dramatically from winter to winter, particularly at Alexandria. A highly significant and positive correlation is found between precipitation along the northern coast of Egypt and the North Atlantic Oscillation for winter rather than autumn for the stations El Salum, Matruh and Port Said. 1-
